Modbus RS485/RS232 to USB converter. Used for connecting Modbus sensors using USB connector of Vutlan monitoring units. Allows communication distance up to 1200 meters.
Allows to monitor up to 32 Modbus RTU devices/meters/sensors. Max. a distance of a daisy chain is up to 1000-1200 meters. Each metered value of a Modbus device is addressed individually using input registers and are shown by the system as virtual sensors. You can configure thresholds and icon representation for these elements.
Board is mounted and connected inside of VT325, VT335, VT805, VT825 monitoring units. Allows to communicate with 1-Wire readers or sensors.
Converter of current loop 4-20mA is used for measurement of constant current on 4-20mA from different sensors and converting data into format of IP monitoring system. The system interface allows you to assign the sensor and to introduce the function data conversion.
